Updated patch to fix a crash if maxsize isn't given, and add a unit test for that.
Possible issues:
* I've tried to emulate object() by calling PyBaseObject_Type. Not sure if there's a more lightweight object for this that just provides the needed __hash__ and __eq__ attributes.
* Not sure if kwd_mark is deallocated correctly.
* Can't quite work out the best way to wrap the C cache_info() method to output the _CacheInfo named tuple. The current mechanism might not be wrapping the attributes correctly. |
